.'o all whom 'it may concern:

Be it known that I, JOHN M. S. Anne son, a citizen of the United States of An'ierica, and residing at Bridgeport in the county of Fnirield and State of Connect-ieut, have invented certain new and usefui 11i iisfovoniente in Push-Button Switches, of which the following is n specification.

My invention relates to electric switches oi the push-button type, and more particu lzirly `to suoli switches of that type as have the rocking parte of the switch mechanism mounted in metal frames secured to tile pm'- eelnn easing.

The object of my invention is to provide means whereby Such rnete frames muy be securely lielil from being' worked ioose in the porcelain by tlie Snap `fiction of the mechanism when the switch is actuated.

In the accompanying drawing, have shown `my inventizvn as applied.. by way of il'lneixition, to the pmt button switch for which Curl Eri-e [im wn nppiied for a patent Muy 1915. Serml No. 26,782', but it will be understood that mv invention may be employ/eel in other constructions.

.in this drawing; Figure 1 is a transverse section of the swim-ii on the iine 3-f Fig. 2; Fig. 2 is :i inse view, with the inse plate and insulatingsheet removed; Fig; f3 is n section on ilee line 3*-3? Fig'. 2; and Fig. 4 is aperspevtive view of the metal frame on which the moving parts of the switch are monntefi.

The eup-siiaped easing A of 'poreelain or other insulating` .material may have at the corners (three in the illustration) binding posts 10, 10, near the surface for tlie bind ing wires, and secured to them suitable spring Contact clips 11. To act in conjunc-l tion with these there is a swinging Contact yoke '12, pivoted at 13 in the sides of s. yokeshaped frame 14. This frame has on its opposite sides Yfeet `5 fitting in seats 16 et the bottom of gwoies 17 in the inner faces of the opposite side :ills of the insulating easing A.. The im?, e '14.- is secured in place by crews 18 inserted from the beek through hoies in the pere-eain and Screwed into threaded holes in the feet 15, Figs. 1, imo. 4. In thisl traine is a'iso mounted the cross pin 19, on which the rocking lever 20 ie pivoted te the frame, and to the outer en of this rocking .lever are pioted the site s of the respective push buttons "Z1 in any suitabie w A. central arm Q2 on the sleeking lever :2O netsnpon :1 pin :25, guided in the yoke und surrounded by e coiled spring 24, so that on pushing down the right lionel pnssli button 21, 3, for instance, Athe arm 22 svil compress the spring 2 with a toggie action, until the point of connection o tlxie :usm 22 passes the center line, whereupon the reaction of the spring 24 Wiil throw the Contact yoke 12 over from the position shown in Fig. 3 to a, position where it eo" teets with the ciips 11 at the right heini elite in that figure. But as I have intimated, the details of the switch mechanism ori'n no part of my present invention.

My invention relates essentiely to the provision of means 'whereby the frame 111 may be heid securely against tendency to work the securing screws 1'8 loose by the rocking and sna Yaction of the i'iriovng!4 parte of the switch. or this purpose, fxedy attach to the outer p irt or arci; of the fume 14, sie by riveting or other means, a cross bei' whose opposite ends enter and snugly fit into the grooves 1? in theside wail of the insulating;r case and, bearing against the walls of seid grooves, at a distance from the screws 18, will eieetnsillvcounteract any tendency of the frame 14 from rocking upon its feet 15 us the switch mechanism is snapped back and forth.

I claim as my invention :-n

1. A push tuition switch, having im insnlating seeing with rocking: switch mecha nism., e fixed frame in which said meehenisn. is mounted und can move, screws for securing the frame in the casing and u cross bar onsaid frame et a distance romvsaid securing screws and engaging thev casing,

2. A push button switch, having a yokeshaped frame with feet, switch mechanism mounted in the frame, an insulating casing havingvsde grooves and seats for he feet of 5 the frame and a cross bar on the frame en- @aging the walls of said grooves, for the purpose described.

In testimony whereof I have signed my name to this specification, in the 'presence of two subscribing witnesses.
